The tremor comes after a 7.5-magnitude and subsequent tsunami struck off the Indonesian island of Sulawesi — around 1,000 km northeast of Situbondo — last month, killing more than 2,000 people.

A string of earthquakes in Lombok in eastern Indonesia killed more than 550 people over the summer.

Indonesia, one of the most disaster-prone nations on earth, straddles the so-called Pacific “Ring of Fire”, where tectonic plates collide and many of the world’s volcanic eruptions and earthquakes occur.

The head of Indonesia’s geophysics agency said there had been no reports of casualties or damage, although information was still being gathered, but the earthquake “didn’t trigger any tsunami”.
